Horizontal installation
For horizontal installation, the preferred orientation is to have the electronics installed to
the side of the pipe. In liquid applications, this ensures any entrapped air or solids do not
strike the shedding bar and disrupt the shedding frequency. In gas or steam applications,
this ensures that any entrained liquid (such as condensate) or solids do not strike the
shredder bar and disrupt the shedding frequency.
High-Temperature installations
Install the meter body so the electronics are positioned to the side of the pipe or below the
pipe as shown in
Figure 3 - 2 . Insulation may be required around the pipe to maintain an
electronics temperature below 185 °F (85 °C).
Steam installations
For steam applications, avoid installations such as the one shown in Figure 3 - 3 . Such
installations may cause a water-hammer condition at start-up due to trapped condensate.
The high force from the water hammer can overstress the sensing mechanism and cause
permanent damage to the sensor.
